    Description

      During a discussion a lunch today at LUG we were talking about the work being done on DOM/DNE/PFL/FLR. We were also talking about Lustre becoming more than just a scratch file system and it occurred to me that one thing that really hampers that concept is the vulnerability of metadata in its present state. 

      I don't recall metadata replication ever being mentioned but I think that I would be a valuable feature to be explored.
